It must show %CE%A0 etc. instead of Greek characters in URL. Actually you have to urlencode() any values in the query string of your URL. I did not use Smarty, but I suppose that "|url_encode" in your code means exactly this - values urlencoding.

Only a subset of ASCII characters are allowed in URLs. Non-ASCII characters must be escaped using the percent-escape method, which is also called URL encoding in programming. Every non-ASCII character is converted into its equivalent hexadecimal value, preceded by a percent (&#37 character. Check the Wikipedia article on Percent Encoding for a broader view of the topic.

Note however, that IRIs (International Resource Identifiers) which allow for non-ASCII characters in URLs are gaining rapid support amongst browser vendors. Opera 9 and Firefox 3 are perfectly supporting IRIs, and IE7 claims that too but it never worked for me.

Even though the above code works fine on English section, on non-English languages like Greek for example I'm getting a 404 error even though the link is displayed correctly when pointing the cursor on it.
